Engaging care partners of persons living with dementia in acceptance and commitment therapy (ACT) programs: a scoping review

OBJECTIVES

Acceptance and commitment therapy (ACT) is a relatively new type of psychotherapy effective for treating depression and anxiety amongst family care partners of persons living with dementia [PLWD]. However, care partner engagement in mental health services is low and specific guidelines for designing ACT programs for care partners of PLWD do not exist. The purpose of this scoping review was to examine patterns in care partner engagement in ACT programs to identify program factors potentially influencing engagement.

METHODS

A comprehensive scoping review according to Arksey and O'Malley's framework was followed. Databases and grey literature were searched for primary studies of ACT programs with care partners of PLWD. Data were charted and synthesized.

RESULTS

Ten studies met inclusion criteria and were analyzed. Amongst these, engagement was highest in three ACT programs that were delivered individually, remotely and were therapist-led or supported. Conversely, engagement was the lowest in two ACT programs that were self-directed, web-based and had minimal or no care partner-therapist interaction. Program factors perceived as influencing engagement included tailoring and personalization, mode of delivery and format, therapeutic support and connectedness, program duration and pace.

CONCLUSION

Findings from this review suggest that care partners engagement may be promoted by designing ACT programs that focus on the therapeutic client-therapist relationship, are delivered remotely and individually. Future research should focus on evaluation of best implementation practices for engagement and effectiveness.

Nursing students' experiences of a post-licensure practical nurse bridging program: a qualitative systematic review

OBJECTIVE

The objective of this systematic review was to synthesize qualitative evidence on students' experiences of a post-licensure practical nurse to registered nurse bridging program.

INTRODUCTION

A worldwide shortage of registered nurses has prompted governments and educational institutions to develop alternate pathways to nursing licensure. One strategy used to increase the supply of registered nurses is bridging programs. Such programs grant practical nurses academic credit for previous educational and practical experience, which allows them to complete a bachelor of nursing degree in a shorter length of time. Understanding the experience of students enrolled in bridging programs will help identify their specific needs and the educational support needed for them to successfully transition into the registered nurse role.

INCLUSION CRITERIA

This review considered qualitative studies that examined the experiences of practical nurses enrolled in bridging programs. Studies published in English were included with no date limits applied to the searches.

METHODS

The literature search was conducted in CINAHL, MEDLINE, Embase, and ERIC. The search for unpublished articles included ProQuest Dissertations & Theses and GreyNet International. Papers were screened independently by 2 reviewers against the inclusion criteria. Papers that met the criteria were appraised using the JBI critical appraisal checklist for qualitative research. Key findings were extracted from the included studies using a standardized tool and classified as unequivocal or credible. The review followed principles of meta-aggregation in line with the JBI approach. The final synthesized findings were graded according to the ConQual approach for establishing confidence in the output of qualitative research synthesis.

RESULTS

Twenty-four studies, published between 1989 and 2020, were included in the review. A total of 83 findings were extracted and aggregated into 11 categories. From the 11 categories, 4 synthesized findings were developed and are summarized as: i) growth through professional advancement reflects that bridging students report personal growth and professional transformation when they return to school and study to become a registered nurse; ii) need for support indicates that bridging students recognize and appreciate a need to have positive support networks in their lives, mainly with their family, co-workers, and classmates; iii) expecting more reflects that, as adult learners with prior nursing experience, bridging students anticipate receiving more support from the educational institutions and higher levels of clinical expertise and competence amongst faculty than what is provided; and iv) finding balance indicates that bridging students struggle to balance and manage multiple roles and responsibilities in their lives as they return to school to study to become a registered nurse.

CONCLUSION

The findings of this review highlight that, as adult learners with prior nursing experience, when post-licensure practical nurses return to study there is often a need to balance multiple roles and responsibilities. It is with the support of family, co-workers, classmates, and faculty that bridging students are able to manage competing personal and academic demands. While many bridging students express disappointment with some of the learning opportunities and/or faculty expertise associated with the nursing program, they ultimately achieve growth through both personal and professional advancement upon program completion and becoming a registered nurse.

Education and training for infection prevention and control provided by long-term care homes to family caregivers: a scoping review protocol

OBJECTIVE

The objective of this review is to map the infection prevention and control education and training that long-term care homes use with families during a pandemic or infectious outbreak.

INTRODUCTION

During the COVID-19 pandemic, restrictions were imposed on visits to long-term care homes to decrease the risk of virus transmission. These restrictions had negative consequences for both residents and families. A scoping review of infection prevention and control education and training used with families will inform family visitation practices and policies during future infectious outbreaks.

INCLUSION CRITERIA

This review will examine literature describing infection prevention and control education and training provided to families in long-term care homes. Research and narrative papers, including experimental, quasi-experimental, descriptive observational quantitative and qualitative studies, reviews, text, policy, and opinion papers, will be considered for inclusion.

METHODS

A 3-step approach will be followed, in line with the JBI methodology for scoping reviews. Published literature will be searched for in databases including CINAHL, Embase, ERIC, MEDLINE, and AgeLine. Published and unpublished papers will be considered from 1990 to the present, in English or in French. The World Health Organization, Centers for Disease Control, and the Public Health Agency of Canada websites will be searched for unpublished and gray literature. Two authors will independently review and assess studies for inclusion and extract the data. The findings will be charted in a narrative summary and tables.

Experiences of faculty and staff nurses working with nursing students during clinical placement in residential aged care facilities: a systematic review of qualitative evidence

OBJECTIVE

The objective of this review was to synthesize evidence on the experiences of faculty and staff nurses working with nursing students in clinical placement in residential aged care facilities.

INTRODUCTION

Nursing education helps prepare students to provide quality care to older adults. Nursing programs across the globe are championing the integration of content on the care of older adults into their curricula as well as recognizing the value of clinical placements that focus exclusively on this population. Staff nurses who work in residential aged care facilities often work alongside students. In this role, they can support faculty and mentor students. This review explored faculty and staff experiences of nursing student placements in such facilities.

INCLUSION CRITERIA

This review considered qualitative studies that address the experiences of faculty and staff nurses working with nursing students in residential aged care facilities. Studies published in English from 1995 onward were included.

METHODS

The literature search was conducted in CINAHL, MEDLINE, Embase, and ERIC. The search for unpublished articles included Proquest Dissertations and Theses and Google searches of the Canadian Nurses Association and American Nurses Association websites. Papers were screened by two reviewers independently against the inclusion criteria. Those meeting the criteria were appraised using the JBI critical appraisal checklist for qualitative research. Key findings from included studies were extracted using a standardized tool and classified as unequivocal, credible, or not supported. This review followed the principles of meta-aggregration in line with the JBI approach.

RESULTS

Six studies, published between 2001 and 2017, were included in the review. A total of 32 findings were extracted and aggregated into nine categories. From the nine categories, four synthesized findings were developed: i) students enhance the environment, whereby faculty and staff perceive that student presence enhances the residential aged care work and living environment, ii) effort is required by faculty and staff to make the experience work, reflecting a need for faculty and staff to accept and work with negativities, iii) residential aged care facilities provide rich learning experiences, indicating an appreciation for available learning opportunities, and iv) importance of a residential aged care-academic partnership for a collaborative approach in creating positive experiences for faculty and staff working with students in this setting.

CONCLUSION

Faculty and staff experiences highlight that residential aged care has the potential to provide students with valuable learning experiences, including how to provide comprehensive and quality nursing care to older adults. A lack of resources in residential aged care inspires faculty and staff to be creative in how they work with students. However, working with students can be challenging for faculty who lack interest and expertise in caring for older adults in this setting. Additionally, staff can become frustrated when they perceive that students do not value the learning opportunities that are available or do not appreciate the expertise required to work with older adults. Partnerships between residential aged care facilities and academic programs can ensure that faculty and staff have the support and resources required to optimize the clinical placements for students.

Hospital-based patient navigation programmes for patients who experience injury-related trauma and their caregivers: a scoping review protocol

INTRODUCTION

Patients who experience injury-related trauma tend to have complex care needs and often require support from many different care providers. Many patients experience gaps in care while in the hospital and during transitions in care. Providing access to integrated care can improve outcomes for these patients. Patient navigation is one approach to improving the integration of care and proactively supporting patients and their caregivers as they navigate the healthcare system. The objective of this scoping review is to map the literature on the characteristics and impact of hospital-based patient navigation programmes that support patients who experience injury-related trauma and their caregivers.

METHODS AND ANALYSIS

This review will be conducted in accordance with Joanna Briggs Institute methodology for scoping reviews. The review will include primary research studies, unpublished studies and evaluation reports related to patient navigation programmes for injury-related trauma in hospital settings. The databases to be searched will include CINAHL (EBSCO), EMBASE (Elsevier), ProQuest Nursing & Allied Health, PsycINFO (EBSCO) and MEDLINE (Ovid). Two independent reviewers will screen articles for relevance against the inclusion criteria. Results will be presented in a Preferred Reporting Items for Systematic Reviews and Meta-analyses for Scoping Reviews (PRISMA-ScR) flow diagram and follow the PRISMA-ScR checklist. The extracted data will be presented both tabularly and narratively.

ETHICS AND DISSEMINATION

Ethics approval is not required, as the scoping review will synthesise information from publicly available material. To disseminate the findings of this review, the authors will submit the results for publication in a medical or health sciences journal, present at relevant conferences and use other knowledge translation strategies to reach diverse stakeholders (eg, host webinars, share infographics).

Teaching strategies and activities to enhance students' clinical placement in residential aged care facilities: a scoping review

OBJECTIVE

The purpose of this scoping review was to examine teaching strategies and activities used in nursing students' clinical placement in residential aged care facilities.

INTRODUCTION

Population aging necessitates that nursing curricula ensure student interest and commitment to working with older adults. While searching for suitable clinical placements that provide students with opportunities to care for older adults, nursing programs have turned to residential aged care facilities. Studies show that carefully planned placement in these environments supports students' needs and offers rich learning possibilities.

INCLUSION CRITERIA

This review examined intentional teaching strategies and activities used during student placement in residential aged care facilities, and considered research and textual papers on the subject. The strategies and activities included those that took place prior to, during, or after the experience.

METHODS

The review included qualitative and quantitative research reports as well as text and opinion papers. Only research reports and papers published in English from 1992 to August 2019 were included. The databases searched were: CINAHL (EBSCO), MEDLINE (Ovid), Academic Search Premier (EBSCO), Embase (Elsevier), ERIC (EBSCO), ProQuest Dissertations and Theses, and Google (with advanced search strategies). Two independent reviewers screened citations for inclusion while a third reviewer resolved discrepancies. A table was developed for data extraction to record data relating to the review objective. Specific data extracted included the details on research design, geographical location, year of publication, description of the teaching strategy or activity.

RESULTS

Of the 84 research reports and papers that were eligible for full-text review, only 25 (30%) were included in the final set. Sixteen papers were research reports including a variety of qualitative, quantitative, and mixed method designs. The remaining nine were textual papers and included frameworks, descriptions, and evaluations of a teaching strategy or activity. Most research reports and papers identified more than one strategy and/or activity used concurrently. The use of care staff as student mentors and facility orientation for students were the two most common strategies and activities reported.

CONCLUSION

A range of teaching approaches during clinical placements in residential aged care facilities was revealed. These approaches targeted students, staff of aged care facilities, and nursing faculty. Collaborative efforts between aged care facilities and educational institutions allowed for the pooling of resources and the delivery of teaching approaches to students and the engagement of care staff. Many of the approaches were co-designed by educational programs and residential aged care facilities. The number of approaches that used more than one teaching strategy and/or activity reflects an appreciation for the importance of student placements and the complexities of aged care facilities. A lack of longitudinal or evaluative research highlights a gap in the literature. There is a need for further work to understand and evaluate the long-term effects and benefits of teaching strategies and activities used to enhance students' clinical placements in resident aged care facilities.

Increasing Student Attendance at Library Workshops: What the Data Tells Us

With attendance rates at library workshops and events in decline, the authors looked to data from practice to help the field move forward. Using survey responses from providers of 161 library workshops across Canada and the United States, the authors examined 10 key variables that are widely believed to impact attendance rates (topic, month, time, duration, advertising, location, target audience, series status, buy-in, and incentives). Analysis of the responses highlights several trends in attendance and offers a better understanding of what students are looking for from extracurricular educational opportunities like those provided by libraries.

Faculty and nursing staff experiences and perceptions of nursing students' clinical placements in residential aged care facilities: a qualitative systematic review protocol

OBJECTIVE

The objective of this review is to synthesize evidence on the experiences and perceptions of faculty and staff nurses toward nursing students' clinical placements in residential aged care facilities.

INTRODUCTION

Nursing education plays an important role in preparing students to provide quality care to older adults. Recent reports suggest that nursing programs across the globe are championing the integration of content on the care of older adults into their curricula as well as recognizing the value of clinical placements that focus exclusively on care for older adults, such as in residential aged care facilities. Student experiences in residential aged care facilities can play a significant role in helping shape professional identity as well as how the setting is viewed. Student interactions with nursing faculty and staff in the residential care learning environment are both recognized as being influential in this process. This review seeks to explore faculty and staff experiences and perceptions of nursing student placements in such facilities.

INCLUSION CRITERIA

This review will consider qualitative studies that address the experiences and perceptions of faculty and staff nurses who work with nursing students in residential aged care facilities. Studies published in English and from 1995 onward will be sought.

METHODS

Two reviewers will independently appraise studies and extract qualitative data using the JBI standardized critical appraisal and extraction instruments. Findings from the review will be categorized according to similarity in meaning, and categories subjected to a meta-synthesis to produce a single comprehensive set of synthesized findings.

Teaching strategies and activities used for students' clinical placement in residential aged care facilities: a scoping review protocol

OBJECTIVE

The objective of this scoping review is to examine and map current knowledge of teaching strategies and activities used with nursing students during clinical placements in residential aged care facilities.

INTRODUCTION

Residential aged care facilities provide opportunities for nursing students to develop skills and interest in caring for older adults. Studies that address students' clinical placements in these settings highlight the benefits of and concerns with their experiences. Insight into the state of knowledge regarding teaching strategies used in residential aged care facilities could benefit nursing education programs and help to ensure student learning is maximized.

INCLUSION CRITERIA

This scoping review will consider research and narrative reports on teaching activities and strategies used by nursing faculty and residential aged care facility staff in teaching nursing students. The concepts of interest include planned and intentional activities and strategies used to facilitate student learning and student clinical experiences. A clinical experience is defined as when a student enters a residential aged care facility and is assigned an individual or individuals to care for.

METHODS

This scoping review will aim to locate published and unpublished literature employing a three-step search strategy. Only papers published in English from 1992 onward will be included. Data extracted from eligible papers will include details on the participants, context, strategy, activity and outcomes. Extracted data will be reported in a tabular form and presented narratively to address the review objective.

An umbrella review of clinical practice guidelines for the management of patients with hip fractures and a synthesis of recommendations for the pre-operative period

AIM

The aim of this review was to locate, retrieve and critically appraise practice guidelines for the management of hip fractures. Given increasing evidence that the early recognition and management of these fractures is integral to achieving optimal outcomes, recommendations for the pre-operative period were synthesized and compared.

BACKGROUND

Hip fractures are associated with high rates of adverse outcomes and high healthcare costs which has resulted in the development of multiple practice guidelines to inform clinical decision-making.

DESIGN

An umbrella review of practice guidelines was conducted which included a critical appraisal using the Appraisal of Guidelines, Research and Evaluation-II instrument and a synthesis of pre-operative management recommendations.

DATA SOURCES

Multi-phased search for practice guidelines published in English using three bibliographic databases; three guideline network websites and three healthcare safety and quality organization websites with no date limit applied. Search was supplemented by contacting front-line knowledge users and content experts.

REVIEW METHODS

Steps for evidence-informed practice were followed: form question then search for, appraise and synthesize the evidence.

RESULTS

Five practice guidelines were appraised revealing significant variability in quality. The largest variability was in "rigour of development". Recommendations for pre-operative management were grouped into six categories: timing of surgery, expedited patient management, identification and treatment of correctable co-morbidities, pain management, preventative measures and multidisciplinary management.

CONCLUSION

Results of this review illustrate that not all practice guidelines are of equal quality. Given the costs associated with the development and maintenance of high-quality practice guidelines, such work may be more efficiently completed through international collaborations and then adapted for national and regional healthcare contexts.

An unusual case of a brain abscess arising from an odontogenic infection

A brain abscess that originates from an odontogenic infection, although rare, can at times be difficult to diagnose, especially in the context of pain and trismus. We report a rare case of odontogenic infection as a result of an infected maxillary third molar, causing an infratemporal and temporalis collection, resulting in a brain abscess with concurrent cerebritis. This is a clinical case review documenting an uncommon but potentially fatal complication.

Personalized dosing of cyclophosphamide in the total body irradiation-cyclophosphamide conditioning regimen: a phase II trial in patients with hematologic malignancy

This study investigates the efficacy and safety of personalized cyclophosphamide (CY) dosing in 50 patients receiving CY along with total body irradiation (TBI). Participants received CY 45 mg/kg with subsequent therapeutic drug monitoring using Bayesian parameter estimation to personalize the second CY dose to a target area under the curve (AUC) for carboxyethylphosphoramide mustard (CEPM) (a reporter molecule for CY-derived toxins) and for hydroxycyclophosphamide (to ensure engraftment). The mean second CY dose was 66 mg/kg; the total dose ranged from 45 to 145 mg/kg. After completion of this phase II study, we compared participants' clinical outcomes with those of concurrent controls (n = 100) who received TBI along with standard CY doses of 120 mg/kg. Patients receiving personalized CY dosing had significantly lower postconditioning peak total serum bilirubin (P = 0.03); a 38% reduction in the hazard of acute kidney injury (AKI) (P = 0.03); and nonrelapse and overall survival rates similar to those in the controls (P = 0.70 and 0.63, respectively) despite the lower doses of CY administered to most of the patients in the personalized dosage group.

Hematopoietic cell transplantation from related and unrelated donors after minimal conditioning as a curative treatment modality for severe paroxysmal nocturnal hemoglobinuria

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare clonal disorder caused by a somatic mutation of the X-linked phosphatidylinositol glycan class A gene. Allogeneic hematopoietic cell transplantation (HCT) after high-dose conditioning is the only curative treatment; however, it is associated with high treatment-related mortality. Here, we report on allogeneic HCT for PNH after minimal conditioning. Seven adult patients with high-risk PNH underwent peripheral blood HCT from HLA-A-, -B-, -C-, -DRB1-, and -DQB1-matched related (n = 2) and unrelated (n = 5) donors. Conditioning included fludarabine 30 mg/m(2)/d on days -4 to -2 and 2 Gy of total body irradiation on day 0. After HCT, patients were given immunosuppressive therapy with oral cyclosporine starting on day -3 and mycophenolate mofetil starting on day 0. All 7 patients attained durable engraftment. After 28 days, a median of 77% (range, 53%-96%) T-cell donor chimerism was found in bone marrow and peripheral blood. T-cell chimerism increased to 91% (range, 76%-100%) on day +180 and to 100% in all surviving patients after 12 months. All 7 patients attained complete remissions of their disease. Four patients are alive 13 to 38 months after HCT. Three patients died of treatment-related mortality, 1 because of complications after acute pancreatitis and multiorgan failure, 1 because of infection related to chronic graft-versus-host disease (GVHD), and 1 because of bleeding after liver biopsy for late subacute/chronic GVHD. Allogeneic HCT from related and unrelated donors after minimal conditioning is a new and potentially curative option for patients with advanced PNH.

Sirolimus (rapamycin) for the treatment of steroid-refractory acute graft-versus-host disease

BACKGROUND

In a pilot trial we evaluated the toxicity and efficacy of sirolimus (rapamycin) as second-line therapy for the treatment of acute graft-versus-host disease (GVHD) in 21 patients (1-46 years of age) after allogeneic hematopoietic stem cell transplantation (HSCT).

METHODS

All patients were treated with methylprednisolone at 2 mg/kg/day, but failed to respond satisfactorily. Sirolimus was started 19-78 (median 37) days after HSCT when 10 patients had grade III and 11 had grade IV GVHD. The first four patients received a loading dose (15 mg/m2) of oral sirolimus on day 1 followed by 5 mg/m2/day for 13 days. The next 17 patients received either 5 (n=7) or 4 (n=10) mg/m2/day for 14 days without a loading dose. Eleven patients completed the 14-day sirolimus course. Five patients were treated for 9-13 days, two for 6 days, and three for 1-3 days.

RESULTS

Sirolimus was discontinued early in 10 patients because of lack of improvement in GVHD (n=5), myelosuppression (n=2), seizure (n=2), and attending physician preference (n=1). The most common and significant adverse events were thrombocytopenia (n=7) and neutropenia (n=4). Other side effects included increased blood triglycerides (n=8) and cholesterol (n=3). Five patients had evidence of a hemolytic uremic syndrome concurrently with or after sirolimus treatment. Eighteen of the 21 patients received 6 or more doses of sirolimus and 12 responded, 5 with complete and 7 with partial responses. Six of the 12 responders (28% of all patients enrolled) and 1 nonresponder are currently alive at 400-907 days after HSCT, 3 with chronic GVHD. Fourteen of the 21 patients (66%) died 40-263 days after transplant.

CONCLUSION

These data suggest that sirolimus has activity in the treatment of steroid-refractory acute GVHD. However, there was considerable toxicity and further dose optimization studies seem warranted.

Clinical outcome after conversion to FK 506 (tacrolimus) therapy for acute graft-versus-host disease resistant to cyclosporine or for cyclosporine-associated toxicities

This retrospective study describes the outcome in 53 patients who had immunosuppressive treatment changed from cyclosporine (CSP) to tacrolimus for resistant acute GVHD (n = 23), hemolytic uremic syndrome (HUS) (n = 13) or CSP-associated neurotoxicity (n = 17). Tacrolimus was administered at doses of 0.03 mg/kg/day intravenously or 0.12 mg/kg/day orally in divided doses, as tolerated. Median time of conversion to tacrolimus after transplant was day 47. Nineteen patients had treatment changed to tacrolimus for resistant acute GVHD grades III or IV, with the median day of conversion being day 49 after transplant. Two of 20 evaluable patients had a complete resolution of GVHD after changing treatment to tacrolimus, with 18 showing no improvement. Eleven evaluable patients had therapy changed to tacrolimus for CSP-associated neurotoxicity at a median of 36 days after transplant. Eight patients had resolution of neurotoxicity and three had partial improvement. Eleven evaluable patients had therapy changed to tacrolimus for HUS at a median of 46 days after transplant. One patient had complete resolution of HUS and 10 showed no response. Side-effects related to tacrolimus included renal toxicity (34%), neurotoxicity (15%) and HUS (9%). Nine (17%) patients remain alive, including six patients who had therapy changed to tacrolimus for CSP-associated neurotoxicity. While often successful for dealing with neurotoxicity, only a rare patient improved after therapy was changed from CSP to tacrolimus for HUS or resistant acute GVHD.

Methotrexate and cyclosporine for graft-vs.-host disease prevention: what length of therapy with cyclosporine?

One hundred three patients with leukemia, aplastic anemia, or myelodysplastic syndrome were treated by marrow transplantation from genotypically HLA-identical siblings (n = 92) or HLA haploidentical family members differing for one HLA antigen on the nonshared haplotype (n = 11). To prevent graft-vs.-host disease (GVHD), they were administered postgrafting immunosuppression with a short course of intermittent methotrexate with daily cyclosporine for no more than 11 days. Customarily, we have given cyclosporine for 180 days after transplant. In the current study, we asked whether cyclosporine could be stopped earlier without affecting the risk of chronic GVHD. By day 60, patients who never had acute GVHD, or whose acute GVHD had resolved, were randomized to have cyclosporine stopped (n = 52) or continued for the usual 180 days (n = 51). Results were analyzed with a median follow-up of 9.3 years after transplant, and showed that patients in whom cyclosporine was discontinued on day 60 had a significantly more rapid onset (p = 0.001), but not a significantly higher overall incidence of chronic GVHD than those in whom the drug was stopped on day 180 (43 vs. 54%; p = 0.26). Transplant-related mortality was comparable among patients without preceding acute GVHD, regardless of when cyclosporine was discontinued (11% for both study arms). However, transplant-related mortality appeared to increase among patients with preceding acute GVHD in whom cyclosporine was stopped by day 60 (38 vs. 17%). Results suggest that cyclosporine can safely be discontinued early in patients who never had evidence of acute GVHD, while those with preceding acute GVHD would benefit from a longer course of the drug. Because of the relatively small sample sizes, these results would best be treated as promising preliminary findings that should be confirmed in larger randomized studies.

Pregnancies following high-dose cyclophosphamide with or without high-dose busulfan or total-body irradiation and bone marrow transplantation

Patients successfully treated with a marrow transplant often have concerns about fertility and pregnancy. This study was performed to determine pregnancy outcome among patients who had received high-dose chemotherapy alone or with total-body irradiation (TBI) and marrow transplantation for aplastic anemia or hematologic malignancy. Records of 1,326 postpubertal and 196 prepubertal patients currently more than 12 years of age after marrow transplant in Seattle from August 1971 to January 1992 were reviewed to determine the patients with normal gonadal function and pregnancies. Among 708 postpubertal women, 110 recovered normal ovarian function and 32 became pregnant. In addition, nine formerly prepubertal girls with normal gonadal function became pregnant. Among 618 postpubertal men, 157 recovered testicular function and partners of 33 became pregnant. An additional two formerly prepubertal men had partners who became pregnant. Forty-one female patients and partners of 35 male patients had 146 pregnancies after transplant. All 76 patients responded to a questionnaire requesting pregnancy history, outcome, infant birth weight, and congenital anomalies information for all clinically recognized pregnancies. There were 115 live births among 146 (79%) pregnancies. Spontaneous abortion terminated four of 56 (7%) pregnancies for 28 female cyclophosphamide (CY) recipients and six of 16 (37%) pregnancies for 13 TBI recipients (P = .02). Partners of 28 male CY recipients had four of 62 (6.4%) pregnancies terminate with spontaneous abortion, but there were no spontaneous abortions among eight pregnancies of five TBI recipients' partners. Preterm delivery occurred for eight of 44 (18%) and five of eight (63%) live births for 24 CY and eight TBI female recipients (P = .01). This 25% incidence among all female patient pregnancies is higher than the expected incidence of 8% to 10% (P = .0001). The 13 preterm deliveries resulted in 10 low birth weight ([LBW] 1.8 to 2.24 kg) and three very low birth weight ([VLBW] < or = 1.36 kg) infants, for an overall incidence of 25%, which is higher than the expected incidence of 6.5% for the general population (P = .0001). Twelve of the 13 premature infants survive. Congenital anomalies were seen among two of 52 (3.8%) live-born infants of female and six of 63 (9.5%) live-born infants of male patients, which is not different from the 13% of single congenital anomalies reported for the general population. These data demonstrate that clinically recognized pregnancies among women who have received a marrow transplant incorporating TBI are likely to be accompanied by an increased risk of spontaneous abortion. Pregnancies among all women who received a marrow transplant are likely to be accompanied by preterm labor and delivery of LBW or VLBW babies who do not seem to be at an increased risk of congenital anomalies. However, determination of possible adverse effects of parental exposure to high-dose alkylating agents with or without TBI on children born posttransplant requires longer, additional follow-up.

Allogeneic marrow grafts from donors with congenital chromosomal abnormalities in marrow cells

To determine whether siblings with chromosomal abnormalities in marrow cells which are associated with cellular defects (e.g. Down syndrome or heterozygosity for Fanconi syndrome) are suitable donors for allogeneic bone marrow transplants, we have reviewed the patient files at the Fred Hutchinson Cancer Research Center (FHCRC) and carried out a survey among member centres of the International Bone Marrow Transplant Registry (IBMTR). The 57 of 253 (23%) member centres which responded to the survey reported seven transplants from donors with the following conditions: Down syndrome (n = 2), suspected heterozygotes for Fanconi syndrome (n = 3), and 47,XXX syndrome (n = 2), among a total of 5,561 allogeneic transplants from HLA-identical siblings. Adding the three cases seen at the Fed Hutchinson Cancer Research Center among 2,927 HLA-identical sibling transplants during 1992 resulted in 10 transplants among 8,488 cases transplanted overall: four with Down syndrome, four suspected of being heterozygous for Fanconi syndrome, and two trisomy X. Three out of four grafts from siblings with Down syndrome had complications, including poor graft function (n = 2) and graft failure (n = 1). Two of four recipients of marrow from presumed Fanconi syndrome heterozygotes presented with poor graft function and a third recipient developed graft failure after initial evidence of engraftment. The two patients given marrow from siblings with 47,XXX syndrome engrafted uneventfully. The experience reported here shows a low frequency of encountering an HLA-identical sibling donor who has chromosomal abnormalities in marrow cells consistent with Down syndrome or heterozygosity for Fanconi syndrome, about one case among 1,000 transplants. The much higher than expected incidence of graft problems with marrow from such a donor would make it reasonable to look either for an alternative marrow donor or consider an autologous transplant, in case a sibling marrow donor with Down syndrome or heterozygosity for Fanconi syndrome is encountered, although a donor with trisomy X seems acceptable.

Cataracts after bone marrow transplantation: long-term follow-up of adults treated with fractionated total body irradiation

PURPOSE

To determine the risk of, and risk factors for, developing cataracts after bone marrow transplantation.

METHODS AND MATERIALS

Four hundred and ninety-two adults who underwent bone marrow transplantation in Seattle were followed for 2 to 18 (median, 6) years. Before transplantation, patients received a preparative regimen of chemotherapy plus total body irradiation (TBI) (n = 407) or chemotherapy alone, without TBI (n = 85). TBI was administered in a single dose of 10 Gy (n = 74) or in fractionated doses totaling 12-15.75 Gy (n = 333). The risk of cataracts was determined for groups of patients with respect to the type of preparative regimen received and other pretransplant and posttransplant variables.

RESULTS

One hundred and fifty-nine patients (32%) developed cataracts between 0.5 to 11 (median, 2.3) years after transplantation. The probability of cataracts at 11 years after transplantation was 85%, 50%, 34%, and 19% for patients receiving 10 Gy of single-dose TBI, > 12 Gy fractionated TBI, 12 Gy fractionated TBI, and no TBI, respectively (p < 0.0001). Among those developing cataracts, the severity was greater in patients after single-dose TBI (59% probability of surgical extraction) than after > 12 Gy fractionated TBI, 12 Gy fractionated TBI, or no TBI (33%, 22% and 23%, respectively). Patients given corticosteroids after transplant had a higher probability of cataracts (45%) than those without steroids (38%) (p < 0.0001). In a proportional hazards regression model, the variables that were correlated with an increased probability of cataracts were single-dose TBI (relative risk (RR) = 2.46) and steroid therapy (RR = 2.34), while a decreased probability of cataracts was correlated with a nonTBI preparative regimen (RR = 0.41). The yearly hazard of developing cataracts in recipients of single-dose TBI was highest during the third year after transplantation, while in recipients of fractionated TBI, the hazard was distributed among years one through seven. The probability of cataracts in all groups reached a plateau at 7 years after transplantation, after which the development of cataracts was extremely unlikely.

CONCLUSION

TBI is the major risk factor for developing cataracts after BMT. Single-dose TBI results in the highest risk of cataracts. However, the risk of cataracts in recipients of fractionated-TBI is significantly higher than in patients who receive no TBI. In addition to TBI, steroid therapy is an independent risk factor for cataracts after BMT.

What role for prednisone in prevention of acute graft-versus-host disease in patients undergoing marrow transplants?

One hundred forty-seven consecutive patients with leukemia, myelodysplastic syndrome, or aplastic anemia were treated by marrow grafts from genotypically HLA-identical siblings (n = 122) or HLA-haploidentical family members (n = 25). Haploidentical recipients differed from their donors for no more than one HLA locus on the nonshared haplotype. All were given postgrafting immunosuppression with a combination of methotrexate and cyclosporine. In a randomized study we explored whether prednisone administered from day 0 through 35 along with methotrexate/cyclosporine could improve prevention of acute graft-versus-host disease (GVHD). The GVHD incidence in patients not given prednisone was comparable with that previously reported with methotrexate/cyclosporine. Unexpectedly, significant increases in acute and also chronic GVHD were seen in HLA-identical recipients administered prednisone, but not in the small number of patients administered HLA-nonidentical grafts. However, the resultant increase in transplant-related mortality in patients administered prednisone was offset by an increase in leukemic relapse in patients not administered prednisone, presumably related to the absence of a graft-versus-leukemia effect. Therefore, overall disease-free survival of the two groups of patients was comparable, with slightly more than 50% of the patients being alive at more than 2 years after transplantation. We speculated that prednisone adversely affected GVHD prophylaxis, interfering with methotrexate's cell cycle-dependent suppression of donor lymphocyte proliferation in response to host antigens. In a pilot study we explored whether beginning prednisone on day 15, after completion of methotrexate administration, would avoid this adverse effect. The GVHD incidence in patients administered methotrexate/cyclosporine along with "late" prednisone was comparable with that in patients not administered prednisone. We conclude that methotrexate/cyclosporine is effective in decreasing the incidence of grade II through IV GVHD, and that the addition of prednisone to this regimen is not beneficial in recipients of HLA-identical marrow grafts.

Value of day 100 screening studies for predicting the development of chronic graft-versus-host disease after allogeneic bone marrow transplantation

We prospectively evaluated 169 patients with a number of screening studies performed between 71 to 121 days after allogeneic marrow transplantation to detect the development of chronic graft-versus-host disease (GVHD). Group 1 patients (n = 78) were asymptomatic and had normal physical examinations at the time of screening and, with a minimum of 8 years follow-up, have not developed chronic GVHD. Group 2 patients (n = 38) had signs and symptoms of chronic GVHD at time of testing. Group 3 patients (n = 53) were similar to those in group 1 in having no clinically evident GVHD at the time of testing, but later developed clinical chronic GVHD. Using time to an event analysis, we compared patients in groups 1 and 3 to determine which of 17 clinical and laboratory factors evaluated at screening accurately predicted the development of subsequent chronic GVHD. Multivariate analyses showed several factors to have independent predictive value. In the first model, results of oral biopsies were excluded since these were done only in one half of the patients. Predictive factors in this analysis included: (1) histologic findings of GVHD on skin biopsy, relative risk 3.23 (95% confidence interval 1.75 to 5.94), P = .0002; and (2) history of grade II through IV acute GVHD, relative risk 3.12 (95% confidence interval 1.72 to 5.64), P = .0002. When oral biopsy results were included in the second model, independent risk factors included: (1) histologic findings of GVHD on skin biopsy, relative risk 5.96 (95% confidence interval 1.95 to 18.19), P = .0017; and (2) low numbers of immunoglobulin A (IgA)-bearing plasma cells detected by direct immunofluorescence in salivary gland areas on oral biopsy, relative risk 11.53 (95% confidence interval 2.51 to 52.03), P = .0017. Our study demonstrates the value of day 100 screening studies for predicting subsequent development of clinical chronic GVHD.

Long term effects and quality of life in children and adults after marrow transplantation

These studies of late effects associated with marrow transplant preparative regimens demonstrate the need for continued long-term follow-up of these patients. Sequential studies of growth and development in children demonstrate that few endocrine function abnormalities occur after high dose CY, but multiple endocrine abnormalities occur after TBI containing regimens. Children may have decreased growth rates and abnormal development of secondary teeth. Most young adult patients who received CY only have normal gonadal function recovery and may be fertile. Neuropsychological abnormalities, cataracts and secondary malignancies may also develop. Although the marrow transplant preparative regimen may not be the treatment modality solely responsible for the various observed abnormalities, transplant recipients need to be evaluated carefully for many years to determine onset of abnormalities and to initiate appropriate therapeutic interventions which may improve the quality of life of these unique patients.

Antibody-mediated marrow failure after allogeneic bone marrow transplantation

Marrow graft failure observed in association with histocompatibility differences between donor and recipient is often attributed to rejection mediated by host-derived cytolytic T lymphocytes. The data presented in this report indicate that persistent host antibodies specific for donor antigen may also mediate graft failure, either by antibody-dependent cell-mediated cytotoxicity (ADCC), or complement-mediated cytotoxicity. In the case of HLA Class I disparity, where all donor cells express the target antigen, the presence of alpha-donor antibody was associated with complete graft failure and death. In the case of ABO blood group antigen disparity, the presence of alpha-donor antibody resulted in erythroid hypoplasia. The latter cases proved informative insofar as they established that host antibodies could persist for more than 18 months after chemoradiotherapy and impair marrow function.

Factors predicting chronic graft-versus-host disease and survival after marrow transplantation for aplastic anemia

The cumulative incidence of chronic graft-versus-host disease (GVHD) was 48% among 165 patients with severe aplastic anemia who had been discharged from Seattle 3 months after they were treated with marrow grafts from HLA-identical siblings. Estimated 10-year survival was 85%. Preceding acute GVHD had a dominating influence on the development of chronic GVHD. Almost all patients with grades II-IV and 67% of those with grade I acute GVHD developed chronic GVHD. Among patients without previous acute GVHD, three factors were independently correlated with an increased risk of de novo chronic GVHD: increasing patient age, the infusion of buffy coat cells in addition to the marrow, and corticosteroid therapy before transplantation. For example, patients below and above age 20 years who had neither buffy coat cell transfusions nor preceding corticosteroid therapy had an incidence of chronic GVHD of only 4-8%, while those with either buffy coat cell transfusions or corticosteroids or both had incidence rates of 33-70%. The development of chronic GVHD significantly influenced survival. Among 83 patients without chronic GVHD, only one died (on day 150 with interstitial pneumonia), compared to 23 deaths among 82 patients with chronic GVHD. For results of marrow grafting for aplastic anemia to improve, better prevention of chronic GVHD is needed.

Marrow transplantation for patients with acute lymphoblastic leukemia in first marrow remission

Forty-six patients with acute lymphoblastic leukemia (ALL) in first marrow remission underwent allogeneic marrow transplantation between August 1976 and June 1985. Thirty-four patients had no extramedullary disease after remission induction and 12 had extramedullary relapses prior to or at the time of marrow grafting. The conditioning regimen included cyclophosphamide followed by total body irradiation, 9.2-15.75 Gy, administered as a single dose or in six or seven daily fractions. Marrow donors were genotypically HLA-identical siblings. Methotrexate was given as prophylaxis for graft-versus-host disease (GVHD). Forty-four patients had marrow engraftment. The incidence of grades II-IV acute GVHD was 52%. Clinical chronic GVHD occurred in 21 patients. Eighteen patients are alive 1-9 years (median = 4.2 years) after marrow grafting, 15 of whom are in continuous complete remission. The estimated probability of relapse within 2 years (+/- standard error) is 41 +/- 9% and the probability of relapse-free survival at 5 years is 28 +/- 7%. Major causes of death were recurrent leukemia, acute GVHD and interstitial pneumonia. Actuarial probabilities of survival, relapse and disease-free survival were not significantly different between those patients who did and those who did not have extramedullary disease after attaining first marrow remission.

Marrow transplantation: what determines success or failure of hematologic reconstitution?

The technique of marrow transplantation serves to replace diseased marrow by normal hemopoiesis. Successful restoration of hemopoiesis is predicated upon the ability of the preparative regimen to ablate both the diseased marrow and the host immune system and upon the capacity of the injected undifferentiated self-renewing stem cells to produce progeny. If these conditions are met, hemopoiesis and an immune system consisting almost exclusively of donor cells will be established although a minority of patients may show a mixture of host and donor cells. If not, graft failure may ensue, a clinical syndrome having at least two etiologies: spontaneous graft resistance and transfusion-induced sensitization. The present report contrasts the immunological findings made with successful hemopoietic engraftment to those seen with graft failure.

Treatment of aplastic anemia with antithymocyte globulin, high-dose corticosteroids, and androgens

A total of 46 patients with aplastic anemia (34 severe; 12 moderate) were treated with antihuman thymocyte globulin (ATG), high-dose methylprednisolone, and oxymetholone. Early symptoms of ATG toxicity included fever, rash, and bronchospasm. Signs of serum sickness also developed in 23 patients. Complications associated with high doses of steroids were hyperglycemia, hypertension, fluid retention, gastrointestinal hemorrhage, and aseptic necrosis of the hip. Other morbidity possible associated with steroid administration included seizures, arrhythmias, and headache with papilledema. Studies of elevated liver function necessitated discontinuation of androgen therapy in eight patients. A complete or partial hematological response was noted in 19 patients (41%). Of these, three have had recurrent cytopenias, of whom one has developed a myelodysplastic syndrome. There are currently 34 patients surviving, and 12 who have died. Actuarial survival at three years is 65%. These response and survival data are comparable to those of previous trials using ATG and androgens without high-dose steroids. A prospective, randomized trial is needed to determine whether the addition of high-dose corticosteroids to ATG does significantly increase the rate and frequency of response in order to justify the toxicity of this additional immunosuppressive therapy in the treatment of aplastic anemia.

Hyperacute graft-v-host disease in patients not given immunosuppression after allogeneic marrow transplantation

Sixteen patients with leukemia in relapse or second to third remission, 5 to 27 years old (median, 17), were given cyclophosphamide (60 mg/kg X 2) and total body irradiation (2.25 Gy for each of seven days) followed by unmodified marrow grafts from HLA-identical siblings. Patients did not receive posttransplant immunosuppression and were followed a median of nine months (range, 5-17). Prompt engraftment was sustained in 12 patients with a median time of 16 days (range, 10 to 63) to achieve 500 neutrophils/mm3. One patient failed to engraft, one had delayed engraftment, and two had late poor graft function. All 15 with engraftment developed moderate to life-threatening graft-v-host disease (GVHD, eight grade II and seven grade III-IV). This syndrome was hyperacute (median onset eight days [range, 7 to 29] posttransplant) and manifest by severe skin disease (14 patients at stage 3 and one at stage 4), fever (ten patients), and liver (four patients, stage 3-4) or gut (four patients, stage 3-4) involvement. Serial tissue biopsies confirmed acute GVHD in 13 of 15 patients. Ten were treated with antithymocyte globulin and cyclosporine (four survive), and four with corticosteroids (two survive). Actuarial survival to 17 months was 37%. Causes of death included interstitial pneumonia (four), infection (three), graft failure (one), venocclusive disease (one), and relapse of leukemia (one). Age-matched controls receiving standard methotrexate after transplant had comparable relapse-free survival but only a 25% incidence of grade II-IV acute GVHD (P less than .0001). We conclude that deleting posttransplant immunosuppression is associated with frequent and severe hyperacute GVHD, infectious complications, and occasional poor graft function.

Recurrence of acute leukemia more than two years after allogeneic marrow grafting

The records of 232 patients with acute leukemia in continuous complete remission at two years after a marrow graft from genotypically or phenotypically HLA-identical family member were reviewed. With a followup time of 2-14.2 years, 17 patients have developed recurrent leukemia 2.0-6.3 years after grafting. No relapses have occurred beyond 6.3 years. Actuarial analysis shows a low but significant risk of recurrence of leukemia more than two years after grafting. These data suggest that the majority of the disease-free patients have had their original leukemic clone eliminated. It is important to study the leukemic cells in patients who suffer a relapse more than two years after grafting to determine whether the leukemia is of host or donor origin.

Marrow transplantation for treatment of pregnancy-associated aplastic anemia

This report describes the results of marrow transplantation in four patients with aplastic anemia during the last trimester of their pregnancies. All patients were treated with supportive care until delivery. Because of persistent severe aplasia, marrow transplantation was then performed 1.6-11.0 months postpartum. Marrow donors were HLA-identical siblings. Although all were at increased risk for graft rejection because of their pregnancies as well as their long transfusion histories, two patients were successfully engrafted and now survive 12 and 95 months after transplant. The other two patients rejected their grafts despite attempts at second or third marrow infusions. Both died of infectious complications, 42 and 111 days after transplant.

Deposition of IgM and complement at the dermoepidermal junction in acute and chronic cutaneous graft-vs-host disease in man

The presence of cutaneous immunoglobulin and complement was investigated in 88 patients with and without graft-vs-host disease (GVHD) after transplantation of bone marrow from HLA identical siblings for the treatment of acute leukemia or aplastic anemia. For comparison, skin biopsies from the patients obtained before transplantation, from 58 healthy individuals (mostly marrow donors) and from four syngeneic marrow recipients were studied. A direct immunfluorescent staining technique was used. Dermo-epidermal IgM deposits were found in 11% of healthy individuals and patients before grafting but were present in 86% of patients with chronic and 39% of patients with acute GVHD. Patients with allogeneic grafts who never had GVHD or who had recovered from it and patients with syngeneic grafts showed findings not different from those in healthy individuals. Findings similar to those with IgM, although less striking, were made for C3, i.e., patients who had chronic or acute GVHD had a high incidence and intensity of C3 deposits at the dermo-epidermal junction. This observation raises the possibility that humoral immunity is involved in the development of GVHD.

Recovery from aplastic anemia following attempted marrow transplantation

A 23-year-old man with severe idiopathic aplastic anemia was prepared for marrow transplantation by the administration of cyclophosphamide (CY) 50 mg/kg on each of 4 days. He then received an intravenous infusion of 9.5 x 10(9) marrow cells from an HL-A matched and mixed leukocyte culture non-reactive sister. The graft was successfully established as shown by cytogenetic studies but was rejected after approximately 4 weeks. In preparation for a second transplant he was given procarbazine 12.5 mg/kg and goat antihuman thymocyte globulin (ATG) 7 mg/kg administered on alternate days for a total of 4 doses of each agent. At the end of this therapy his white blood cell count was noted to be going up and the second transplant was not carried out. Complete hematologic recovery of host type marrow ensued and persists now 20 months later. The various pathophysiologic mechanisms that may be involved are discussed.
